The effect of chickpea processing (soaking, soaking plus cooking and dry heating) on the content of available carbohydrate (monosaccharides, disaccharides and starch) and antinutritional factors (a-galacto-sides and trypsin inhibitor activity) was studied. Soaking produced a reduction in available carbohydrates (19-20%) and α-galactosides (16-27%), and either did not affect or caused a slight reduction of trypsin inhibitor activity (TIA) in chickpeas. Soaking plus cooking brought about a larger decrease in available carbohydrates (23-24%) and α-galactosides (45-58%), and completely eliminated TIA. Dry heating caused a 24% reduction in available carbohydrates, a 46% decrease in α-galactosides and a 27% decrease in TIA. Overall, cooking the presoaked seeds in water, acidic or basic solution seems to be adequate to obtain a chickpea flour with a large reduction in antinutritional factors (α-galactosides and TIA) and also a high level of available carbohydrate content.
